It is indeed a rare thing to have common sense nowadays. I've dealt with so many people with no common sense and it is really upsetting because when you treat someone the way you want to be treated, they ended up treating you even worst.
I really feel that those who doesn't have common sense is either a selfish fathermucker or they were raised in an environment that doesn't requires them to actually use their brains. I mean how ignorance can you be to not have an ounce of common sense or common courtesy. When you borrowed money, pay them back. If you promised something, fulfill it. If you're at someone's place, respect their place. Respect people's time and many other things that people failed to take it seriously.
Not that I'm perfect and I too sometimes forgot about things and overlook on things but when it happened way too often, that mean something is really off with you as a person. You need to take a step back and look at yourself on why are people been avoiding you and why is that you always unhappy when you're with someone.
So do you agree that common sense is not that common anymore? Have you encountered someone with zero common sense? It's kinda hard to deal with right?
P/S: Yes you got zero common sense. You know who you are.
